Abstract
This study was undertaken to examine the effect of different nitrogenous sources (poultry litters, poultry litter + urea and urea only) with or without Saccharomyces cervicea SC supplementation in manufacturing of feed blocks on daily intake, daily gain and digestibility. Twenty four rams with 42.50kg average weight and 1.2-1.5 years old were randomly divided into 6 equal groups with 3×2 factorial experiment .By using of feed blocks with different nitrogenous sources did not significantly affect daily intake of straw, concentrate and total daily intake, as well as final body weight and total gain, while daily feed blocks and gain were significantly (p<0.05) effect. The effect of SC supplementation on intake lacked significance for all feed stuffs. Feed blocks with different nitrogenous sources did not significantly affect nutrient’s digestibility, except for crude protein and ether extract. The SC supplementation had significant (p<0.05) effect on most nutrient’s digestibility, except for crude protein and ether extract. In conclusion blocks containing urea+ yeast SC represented the best formula in which better performance of rams can be achieved.
